2002 LS V8 said:I have a 2002 V8 with ~30,000 miles. I have recently taken a few trips with just highway miles. I am only getting a max of 21-22 mpg and this is averaging 65-75 mph. Is there something I should have looked at in my car? I see you guys getting 25+ and in the two months I have had my car I haven't seen anything near that. My average mpg is somewhere around 16-17 but thats 65% city driving.

KC_Valentine said:Drove 2.5 hours with cruise set at roughly 70-90 the whole way except through small towns to 45 and I topped out at 24.8 MPG. Usually never over 19 city though.
My best mileage was almost 25mpg on the Monday of Memorial Day weekend. That weekend I went to Denton and back three times (~320 miles round trip each time, almost all interstate miles at ~80mph), and my mileage got better every day as the computer learned the new settings. This was calculated mileage, and I filled up a the same Conoco pump each day.z1069 said:Speed?
With long distance highway cruising the V8 will actually be turning less rpm's than the V6 while maintaining the same speed, so the V8 will have very similiar if not alittle better mpg than the V6, but anytime you hit the pedal that all changes.itslmabry said:I travel with my work every day - usually spend about 6 hours on the road. My best mileage was a five hour stint that resulted in 27 mpg. I think that's pretty decent mileage for a V8, and I'll take it over riding in a less powerful car. Of course, if I can't open my doors (see my post) I guess my rides will be much longer.
